D:\big\centos>vagrant init centos7
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

D:\big\centos>vagrant up

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

p24 24、分布式组件-SpringCloud Alibaba-Nacos配置中心-命名空间与配置分组

笔记

• 命名空间
  • 是为了解决配置隔离的问题
  • 隔离开发测试环境
  • 微服务之间配置隔离
• 配置集：所有的配置的集合
• 配置集ID：(DATA ID)类似文件名
• 配置分组
  • 默认所有的配置分组都是default
  • 双十一的时候使用一组,618等等

每个微服务创建自己的命名分组，使用配置分组区分环境,dev,test,pord

内存

xmp

近日发现自己3000mhz的内存条在资源管理器里面显示只有2133mhz

原来是因为xmp没开

参考文献

加内存条

今日发现内存不够用了,便寻思着需要加一个根内存条

按照华硕官方的建议指导手册的建议来插发现，点亮之后发现并没有成功识别第二根内存条(两根内存条参数完全一致)

后来发现有可能是插的不牢固(参考文献)

发现真的没插牢,插内存条的时候听见「柯登」一声响，就插牢了

后来发现没点亮,主板的错误码是CC，主板说明书里面也没有描述这个错误

将两根内存条交换反插，发现能成功点亮

点亮之后，报下面这个信息

原来是我开了xmp,F1 重新确认一遍xmp的设置就好了(他会警告你最好cpu要带水冷),F10保存设置并退出，就成功了！

他们的分析$\color{green}{\text{排除了}}$这样的可能性，即：是公司的政治影响力，而非他们的企业社会责任立场让公司获得了$\color{red}{\text{宽大}}$处理，因为那些支持政治运动更多的公司并没有被处以更少的$\color{green}{\text{罚金}}$。

Sentence 68

Sentence 99

At Tulane University’s Tear Analysis Laboratory, Dr. Peter Kastl and his colleagues report that they can use tears to detect drug abuse and exposure to medication, to determine whether a contact lens fits properly or why it may be uncomfortable, to study the causes of “dry eye” syndrome and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants.

Sentence 100

Young people who are still getting started in life were more likely than older adults to prioritize personal fulfillment in their work, to believe they will advance their careers most by regularly changing jobs, to favor communities with more public services and a faster pace of life, to agree that couples should be financially secure before getting married or having children, and to maintain that children are best served by two parents working outside the home, the survey found.

一个正确答案

坑点1:

需要考虑到多项式的值为0的时候,输出为"0"不能有空格"0 "

测试数据中的某个测试点的输出格式错误的测试数据

坑点2:

记得考虑到所有的值都被round了
